If you exchange the H-tone plate against Bb sound board, you get a carillon in F major. The scale is then FGA-Bb-CDEF.
If you exchange the Fis-tone plate against the lower F-sound plate, is the carillon in G major, with no complete G-major scale is available on the carillon.
The bells Spie makes a strong impression, and I often wonder how long the "Plastikgnubbel" that hold the sound bar in place, will keep well. But until now, and I have the instrument a few years, is not yet a "Plastikgnubbel" aborted. The sound is, thanks to the felt pad, very good.
